If I would introduce bitcoin and Bitcointalk forum to a friend of mine,first I would examine the person if he/she has an interest in tech stuff, because learning is the mindset.If the person's mindset is not built on learning about bitcoin that's the first stage that discourages me on introducing bitcoin and this forum to my friends.
Lots of newbies who registered an account on Bitcointalk forum are no longer active all because they couldn't abide to the rules and regulations of the forum.And failure to learn and make contributions on quality post can also discourage a newbie since low quality posts are not merited.Before introducing this forum or bitcoin to any person it could be your friend,you should be security concoius because you don't know the intention of the person.
In addition if I would want to introduce this forum to a friend I will tell the person to read more, contribute less and make quality posts.It is said when your in Rome act like a Roman so every newly registered persons should adapt with other members in this forum.
